## Abstract Lactone von L‐γ‐Hydroxyaminosäuren sind wesentliche Bausteine sämtlicher Toxine des grünen Knollenblätterpilzes (__Amanita phalloides__). Als __N__‐acylierte Derivate (**2a‐g**) racemisieren diese α‐Amino‐γ‐lactone vom Typ **1** am α‐C‐Atom bereits unter schwach basischen Bedingungen be
Substituted a-amino y-lactones were synthesized as potential antibacterial agents. A series of new y-substituted a-aceto and aoximino y-lactones is reported. HE OCCURRENCE of the lactone ring in many Tphysiologically active compounds has been reported throughout the literature. Of interest
## Abstract Die Umsetzung entsprechender α‐Amino‐γ‐lactone mit Phenyllithium führt zu den 2‐Amino‐1,1‐diphenyl‐alkan‐1,4‐diolen **2a–f**, die auch als dihydroxylierte Diphenylethylamine aufgefaßt werden können.
A lacile slereoselcctive melhod Ior the synthesis of y-substituted, y-mnino acids from of amino acids was developed. The key step of the procedurc is complete reduction of Ihe keto functionality of ot-~unino acyl Meldruln's acid by sodium acetoxyborohydride. The resulting amino alkyl Meldrum's acid
